In addition to the main mansion, the property includes four homes, 1,500 trees and an exercise pool for horses.

Newton, 71, his family, and a menagerie of exotic animals downsized in June to a $3 million estate on 20 acres nearby.

Grant Lyon, who is overseeing the property for the Harbers, said the price has risen by $50 million in part because of the improvements CSD made to the property. The new owners added a 14-car garage, remodeled the horse stables, and removed manure.

Lyon imagines the property will appeal to a wealthy equinophile. It can house 60 horses.

“If someone is an avid horse person and wants to live in Las Vegas but still maintain a level of seclusion and privacy, it’s probably the only property that offers that,” he said.

He said the hope is to find a buyer, likely from abroad, who sees the property as a trophy.
